Information display arrangements
First Claim
1. An information display arrangement including a store for information signals indicative of variation of a parameter of a body over each of a plurality of substantially two-dimensional regions in the body, adjacent regions overlying one another to at least a substantial extent, means for displaying individually the information signals relating to at least some of said regions, means for selecting features of interest contained in the displayed information, and means for combining the information so displayed to provide a pseudo three-dimensional display of part of said body with the selected features shown in relief.

Abstract
The data derived from a computerized axial tomographic apparatus in respect of a number of slices through a body are processed to produce a representation of the variation of absorption of X-rays over each slice. The representations are operated upon individually to identify areas which are of reduced interest and/or which are obscuring regions of especial interest. This having been done, the representations for all the slices are correlated to produce a pseudo three-dimensional display of part of the body with the identified areas being displayed with reduced or zero intensity as compared with other areas. Alternatively, the identified and other areas can be represented in different colors.

5. A method of displaying information comprising the steps of:
storing information signals indicative of variation of a parameter of a body over each of a plurality of substantially two-dimensional regions in the body, adjacent regions overlying one another to at least a substantial extent;
displaying individually the information signals relating to at least some of said regions;
selecting features of interest contained in the displayed information relating to said at least some regions; and
combining the information so displayed to provide a pseudo three-dimensional display of part of said body with the delineated features shown in relief.
